DICHLOROBENZENE OR P-DICHLOROBENZENE Chemical compatibility with O-rings, rubbers, & plastics

Dichlorobenzene, including p-dichlorobenzene or para-dichlorobenzene, is a colorless to pale yellow aromatic liquid with the chemical formula C6H4Cl2 commonly used as a solvent and chemical intermediate. This chlorinated hydrocarbon is considered highly toxic and may cause significant skin and respiratory irritation. When evaluating chemical compatibility, O-rings, rubber seals, gaskets, and plastic components should be carefully reviewed, as dichlorobenzene can cause swelling or degradation in certain rubber materials. Proper handling, storage, and protective practices are essential.
